Ukrainian President Petro Poroshenko has said the fighting in the eastern part of his country against pro-Russia separatists costs about $5 million a day that Ukraine could be putting into development.
Poroshenko was speaking to a UN summit on September 27.
Poroshenko said the fighting that began in early 2014 has made Ukraine lose “about one fifth of its economic potential.”
Poroshenko said the Russian-backed insurgency in eastern Ukraine “has led to the emergence of a new form of poverty, sudden or unexpected poverty” for thousands of people.
His remarks come a day before Russian President Vladimir Putin was expected to make his first appearance at the UN General Assembly in a decade.
The Kremlin says Putin wants to focus on fighting extremists in the Mideast during his visit.
Kyiv and its allies, including Washington, want to press Moscow to stop backing the separatists, something the Kremlin denies.
During Poroshenko’s speech, all but one member of the Russian delegation walked out in protest, according to TASS.
